Rolling machine

This four rolls bending machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical.

Top roll is main drive rolls, it can does vertical and level motion, up and down, parallel translation is display. This machine includes pre-bending function.

Down rolls were driven by two cylinders.

Side rolls moved by motor and speed reducer gear.

Down rolls can life vertically, side rolls lift slope, the precision is ≤±0.15mm.

Down rolls rise to hold the plate ends, and side rolls rise slope to finish pre-bending function.

It can bend in symmetric and unsymmetrical type According to two sides positions dispose condition, this type of machine can bend ideal rolls with very less edge once, compare with 3 rolls machine, no need to press machine to do pre-bending.

The control system adopt OMRON from Japan, PLC control the down rolls, two side rolls, tuning frame position ,with touch screen operations.

The displacement transducer of down rolls and two side rolls adopt circum gyrate coder, the transducer movement design reasonable with long operation life and supervisory control.

All the bearing adopt advanced technique, famous brand productions.

Hydraulic cylinder with high precision, excellent airproof, without leakage.
